Incorporating grain-scale processes in macroscopic sediment transport models: a review and perspectives for environmental and geophysical applications

B Vowinckel - Acta Mechanica, 2021 - Springer
Sediment transport simulations face the challenge of accounting for vastly different scales in
space and time that cannot be tackled by a unifying approach. Instead, processes are …

Collision model for fully resolved simulations of flows laden with finite-size particles

P Costa, BJ Boersma, J Westerweel, WP Breugem - Physical Review E, 2015 - APS
We present a collision model for particle-particle and particle-wall interactions in interface-
resolved simulations of particle-laden flows. Three types of interparticle interactions are …

Pairwise-interaction extended point-particle model for particle-laden flows

G Akiki, WC Moore, S Balachandar - Journal of Computational Physics, 2017 - Elsevier
In this work we consider the pairwise interaction extended point-particle (PIEP) model for
Euler–Lagrange simulations of particle-laden flows. By accounting for the precise location of …

Review about PD and breakdown induced by conductive particles in an insulating liquid

C Pan, J Tang, G Chen, Y Zhang, X Luo - High Voltage, 2020 - Wiley Online Library
In insulating liquid, a conductive particle becomes charged through the interaction with a
conductor exposed to an applied field. Then, it migrates in the action of both electric field …

A collision model for grain-resolving simulations of flows over dense, mobile, polydisperse granular sediment beds

E Biegert, B Vowinckel, E Meiburg - Journal of Computational Physics, 2017 - Elsevier
We present a collision model for phase-resolved Direct Numerical Simulations of sediment
transport that couple the fluid and particles by the Immersed Boundary Method. Typically, a …

Magnetohydrodynamic two-phase dusty fluid flow and heat model over deforming isothermal surfaces

M Turkyilmazoglu - Physics of Fluids, 2017 - pubs.aip.org
This paper is devoted to the mathematical analysis of a magnetohydrodynamic viscous two-
phase dusty fluid flow and heat transfer over permeable stretching or shrinking bodies. The …

On the kinematics and dynamics of crystal‐rich systems

GW Bergantz, JM Schleicher… - Journal of Geophysical …, 2017 - Wiley Online Library
Partially molten rocks, often called a mush, are examples of a hydrogranular mixture where
the dynamics are controlled by both fluid and crystal‐crystal interactions. An obstacle to …

VOF-DEM study of solid distribution characteristics in slurry Taylor flow-based multiphase microreactors

Z Peng, L Ge, R Moreno-Atanasio, G Evans… - Chemical Engineering …, 2020 - Elsevier
Solid particle distribution determines the reactor internal phases placement and the contact
mode between catalyst particles and the liquid phase, thus plays a key role in dictating the …
